GUMMEID-TAPE MACHINE.

To all whom it may concern.-

Be it known that I, Fnnnmoi-r Koor-r, a citizen of the United States, residing in Parsons, in the county of Labette and State of Kansas, have invented a new and useful Improvement in Gummed-Tape Machines, of which the following is a specification.

This invention relates to improvements 111 that type of devices known as gummed tape machines, and in which a roll of paper gummed upon one side is rotatably held, the paper being drawn in strips from the roll over a suitable moistening device, thereby dampening the gummed surface, for the purpose of sealing packages with said strlps.

The specific object of the present lmprovements is to prevent the projecting end portion of the strip from falling into the water containing receptacle, and to always hold the same in proper position for grasping between the fingers.

A further object of the invention is to prevent accidental unrolling of the strip, and to check rotation of the roller as soon as the pull upon the paper ceases.

A still further object is to render easy the placing of any rolls in the holder and also to provide for the use of rolls of various widths.

l/Vith these objects in view, the invention consists of the novel features of construction hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which,

Figure 1 is a side elevation partly in section. Fig. 2 is a top plan view of the device. Fig. 3 is a front end elevation. Fig. 4 is a section on the line 4-4 of Fig. 1.

In the above drawings, 1 represents a substantially semi-cylindrical housing, the upper parallel side edges of which are cut away upon an inwardly curving line as indicated at 2, and centrally thereof is formed an open bearing for a shaft 3, said shaft is provided at one end with a collar 4 and at the opposite end with a winged nut 5, thereby preventing longitudinal movement of the shaft upon its bearings. A spool or core 6 is mounted upon said shaft and said spool or core 6 carries a roll 6 of a suitable paper, gummed upon the inner side.

It will be obvious that the shaft 3 can be readily lifted from place, a new roll slipped upon it while removing the nut 55, and easily returned to proper posltion.

The housing is braced and supported at its rear end by suitable standards 7, which are secllred in any desired manner to a base 8. At its forward end an oblique slot 9 is formed transversely in the housing. A bracket 10 also carried by the base 8 is arranged at the front of the housing and is provided with a transverse slot 11, which registers with the slot 9 of the housing, the paper strip traveling downwardly and outwardly through the passage formed by said slots. The bracket 10 is provided with a forwardly and downwardly extending shelf 12, the upper surface of which is a continuation of the bottom wall of the slot 11, so that as the paper leaves the roll it will travel down said shelf and will be guided to a suitable moistening roller 14, mounted in a suitable water receptacle 15, also arranged upon the base 8. The upper end of the bracket 10 has a forwardly extending projection 13, the front edge of which is sharpened to form a cutting blade for the purpose of severing the paper strip.

It will be noted that the shelf 12 not only acts as a guide for the paper to the roller 1 1, but also prevents any slack in the paper from dropping downwardly into the liquid receptacle 15, the said shelf projecting above said receptacle.

In the rear of the housing is a suitable pin 17 upon which is mounted the coiled bow portion of a U-shaped spring 18, the side members of which converge toward their free ends. These said members at their free ends are suitably adapted to receive reduced ends of a roller 19, said roller bearing upon the roll of paper, thereby preventing unwinding of too much paper by checking rotation of the roll of paper as soon as pull upon the paper ceases. The side members of the spring 18 are of such length that the roller 19 is substantially in vertical alinement with the shaft 3 and the pressure of this roller upon the paper immediately above said shaft prevents any danger of said shaft jumping from its bearings during rotation of the paper roll. The roller 19 is readily removable and if it is desired to use paper rolls of varying widths, rollers 19 of different lengths are provided, and by simply substituting a roller of one length for another they will fit paper of different widths.

In case the tape should break inside the housing it is highly desirable that itbe pre vented from dropping down in the housing. Therefore at the front of the housing I hinge a plate of suitable width as shown at 20, said plate normally having its free edge resting on the roll of paper or tape. To prevent the plate from dropping too low down a bracket 21 is provided, and when, by reason of decrease in size of the roll, the paper has permitted the plate 20 to drop into its lowest position, as shown by dotted lines in Fig. 1, the bracket 21 engages the Wall of the casing, and acts as a support for the plate.

To prevent reverse rotation of the mois- Gus H. KEY, A. M. EOKELBERRY.
